An update on my Seville. I was going to order a new headlight since the old one on the passenger side is looking like hell. GMPartsDirect had a price of $363... not bad. Then I add the shipping costs and tax, came out to $453. Soo... I didn't order one. I'll try another one of those headlight kits. Or I'll get a professional to fix it.

But, I did order a new intermediate steering shaft and bearing, front door speaker, and ignition switch. My shaft has been making noises for the longest time and the steering is slightly sloppy. The front door speaker blew a few months ago and is in need of replacement (going to order subwoofer soon). Finally the I'm 85% sure the ignition switch is going bad, so while my dealer is putting all this stuff in I figured they can replace it and get that over with. Pretty happy to get started on my list. Not too much left to do! :)

Ryan, you should contact Bose directly about that speaker. I recall a post from a while back about someone who got a free replacement from Bose because Bose does not want a car rolling around with a crappy sounding speakers. Search for it. I think that guy got a free subwoofer.

Well it's been a crazy month for the 'ol Seville. Had the intermediate shaft changed out, new Bose speaker installed, and my new ignition switch. Price for the labor came out to $300 (got a $100 discount. yay!). Unfortunately, when installing my ignition switch my tech told me my theft module was damaged, and replaced that. However, this has not solved my security light problem; I've been told it's a possible BCM problem, but I'm not throwing any more money at that issue.

An even worse issue was awakening to go to work one morning and seeing a large puddle of water on my drivers seat. After sitting at the dealer for 2 days, I had a newly resealed windshield that didn't cost me a dime. Unfortunately, it still leaks badly. At this moment, it sits at my dealer awaiting a fix (In the meantime, I've got a '08 CTS loaner so I'm not too upset). I believe a new windshield is getting installed at no cost to me, since it has always leaked. I just hope no rust found its way in there.

Nice review, I too have a 2000 STS and mine hasnt givin me a single problem (knock on wood). I love the styling of these cars and actually prefer this body style over the newer redesigned 05+ models. I added a E&G grille and the only thing I wish my 2000 had was the magne-ride suspension, HID headlights, back up sensors, and newer large screen nav system. Everything works great, sunroof is awesome, no trunk leaks, cranks instantly, and only has a very faint shimmy at 67-71mph. Im planning on getting some of the newer 17" wheels with some serious performance meat. Overall I love this car! I got the car with 60,000 miles for $4500 (gotta love recessions lol) and I couldnt be happier!!

It's been an extremely quiet month for the Seville (knock on the beautiful Zebrano wood of course). The car continues to impress with it's power, elegant bodystyle, and it's ride. I continue to enjoy driving this car, and all of my friends and family are impressed with the car. I'm still nitpicky over the crappily assembled interior, which does not fit well in a car costing $53k in 2000.

My only issues this month was a mysterious stalling, which happened a few months back in the same exact spot on the road. I've also experienced a loss of power only once, and I'm attributing both to the crankshaft position sensors, though it has thrown up no codes. My car still has the 60MPH vibration, though I'm getting new tires thrown on soon so I'll get a good road force balance and alignment to hopefully solve both. Of course, I still get a random "Service Theft System" a couple of times a day, which I attribute to a small electrical short that I'm not paying to fix. It doesn't harm the car, and restarting the car always fixes it.

Within the next month, I'm getting a new intake plenum, fuel pressure regulator, possible CKP's, a cleaned throttle body, a re-adjusted drivers door striker, new intermediate shaft bearing installed, new tires with RFB and alignment, and I'll probably go ahead and get some new spark plugs and spark plug boots thrown into the mix; i'll also get my dealer to adjust my glovebox, which is terribly misaligned. In the springtime, I plan on getting a transmission flush w/ filter, a recharged A/C. I'm getting my passenger side headlight polished professionally, getting a few dents fixed, and touching up some paint. After this, the car should be in showroom shape.

What a friggin steal! I payed $10k for my car in June '08 with 54k miles, though it had headgasket work, water crossover done, and a newly resealed bottom end among many other things. I adore the car, and much prefer my bodystyle over the '05+, though the new models drive 10x better. The only feature I wish my car had was the MagneRide, which I have yet to test on a Seville. I plan on keeping the car for another 2 1/2 years, then I'll trade up to a new STS.

Bought some gas.
Washed it.
Bought some more gas.

Been a rough one for both of us! :)

:D I'm glad to see you finally washed the poor girl! ;)

Most of that stuff is just me being a nitpicky bastard. The only real necessary stuff is the CKP's, fuel pressure regulator, and the intake plenum. Everything else is just optional, but I'd like to have it done anyway so I can sleep better at night.

Ryan, are you sure you want to flush your transmission?
I found a simple drain, refill, and new screens safely did the job.
Do you have a budget in mind for all of this work? Sounds pricey.

I might do that suggestion on the transmission. There have been many of them around here that have been ruined due to a service like this, though most of those come from an independent shop and not a dealer.

I don't have a budget for all of this; normally I'd say it would go for something like $1k to $1500 for everything, but since I work at my dealer I get a discount on parts and labor, so I'm guessing it will be around $700-$900 with the tires being the most expensive. I'm most likely going to wait on the spark plugs since they've only got 65k on them. My biggest concern is the fpr and the intake plenum, which is for sure causing my missing idle. I'm not too sure about the ckp right now; The other things are really a tossup, though I want to get them done and get the car as perfect as a 9 year old car can possibly be. She turns 9 years old on 1/22, and I'd like to get all of this work done for her b-day. Deserves it, that's for sure.

Re: 2000 Seville SLS-theft system noise when v.cold

Hi everyone,
I have seen several mentions of the strange noises and the "service theft system" light. I live in Wisconsin and every time it gets below freezing my car makes a terrible noise when I start it, like a "wha..wha...wha....wha" noise that comes from what appears to be somewhere behind the dash near the far left corner of the windshield. It sounds like someone is slowly strangling the alarm system but it is clearly louder on the inside of the car. This is also accompanied by the "service theft system" message and lately also the security light. It only does this for 20 seconds to a couple minutes depending on how cold it is and it only seems to do it on the first start of the day. The alarm system still seems to function properly but this is driving me crazy. Any ideas??? or should I just try to ignore the noise and my boyfriend referring to my sweet ride as a "rickety old Cadillac"??
Also, if there is a better place for this post, let me know...and thanks for any help you can give me.:banghead:

luvmy, Do a search for "aspirator" and "cabin air temperature sensor".
You're looking for the procedure to R&R the sensor and tiny muffin fan behind the 1" square grille just left of the steering column. You go in through the panel at the left (door) end of the instrument panel, the one with the round window duct sealer which mates with the door duct. Listen at the grille during cold start.

If that's not the problem, then look for the A.I.R. secondary injection pump, located in the l/f fenderwell, used to light off the cat on cold start.

Move this up to Seville..............fairly common problem.

:welcome: to the forums!

It's best to post this in the Seville/Eldorado forum which has more traffic. The sound coming from your dash could be the aspirator fan, which over time starts making lots of noise and needs replacement. A new one cost $30 and a search around the site will show how to replace it. Mine makes a similar noise, but it doesn't bother me enough to replace it now.

As for the Service Theft, I'm not sure where you would start. The day after I bought my car in June it randomly lit up on the dash, and my dealer and I are stumped as to what it could be. One tech suggested the BCM, but if that were so the other functions running through it would most likely be fizzling as well. My car might have a slight electrical short causing the Theft message, but I'm not dumping any more money into it. You're message could be something as simple as the theft module, but I'd post in *************** to get more information.

Luvmy, I did a cheap fix on my aspirator fan.
I took off the tiny grill, moved the temp probe wire to the side with needlenose pliars, and stuffed
some insulation down to the fan.
Got me through one cold winter without that grinding noise.
The permanent fix is what Submariner says ... replace the fan, because the bearing goes bad.
Good luck, enjoy your ride.

I'm keeping this thread around as kind of a one year long term test, to see how a Seville ages after it's already 8 years broken in. So far at the almost 7 month mark, the car has given me no motor trouble to speak of. My problems have been with the accessories, mainly the still shining "Service Theft" message, the sometimes bipolar radio, and the aspirator fan which is on it's way out.

Today I took the car in for it's most comprehensive service yet, getting an oil change, new crankshaft sensors, a new intake plenum, a glovebox and drivers door adjustment and few things I'm forgetting. I'm $500 poorer, buy my slightly "off" idle is much improved, though it's still not perfect. With a tuneup coming soon, I expect that to be fixed completely soon. My passenger headlight is still in bad shape, and very soon I will get that fixed, along with some touchup and a few dents that are getting on my nerves. I get new tires next week, most likely cheaper Uniroyal's along with a RFB and alignment. My next service will include the aftermentioned spark plugs and boots, a tranny flush, and a/c service. Other than my gripes, the car is still impressive after 7 months and 11k miles of service. I still stare at it when walking away, which causes most people to look in confusion. They don't get it.

It's been pretty quiet here in the world of Seville, at least until something goes south next week.

My slightly off idle I reported last time... turns out to be a poor camshaft design by GM that effects some early 2000-2001 model year Northstar's. The original owners never gotten it taken care of, and I'm going to continue that trend. It's not worth spending that kinda of money on a 9 year old car. I did get new spark plugs installed and have been using premium gas, so that helps it a little bit.

After my unfortunate blowout, I finally got new tires. Cheapy 225 Uniroyal's (I'm not made of money here). I'm not crazy about them at all. They don't handle well, and make more noise than the Michelin's did (you pay for quality). They ride nice, and 90% of my 65-75MPH vibration is gone. My brakes still vibrate terribly. Guess they need to be resurfaced... again. I'll cross that bridge when the time comes.

The outside of the car looks better than ever! Finally got that foggy headlight cleared up, though it still doesn't look as good as the drivers side. Oh well, not worth spending $500 for a new one. Got a few of my spots touched up with GM touch-up paint. Has some dents on the roof but otherwise, the outside is immaculate.

My problems with the car continue to be the "Service Theft System", a noisy aspirator fan, warped dashpad, and noisy passenger side strut. The fronts will need replacement soon, though I'm hoping I can go another 10k miles before replacing. I'm going with Arnott.

The Cadillac Seville represents everything that is great in America. This car will get you noticed, and that is a good thing. If you’re the type of person who can overlook small things like a slightly cheap interior, less than excellent build quality, and the sticker price, well this is the car for you. Driving a Seville STS will have people turning heads, looking at the car over and over. It will be catching stares from people while you’re washing it in the driveway. It represents power, prestige, and the sense that you’ve made it. Sure, you can get a Lexus, but when have you ever caught yourself staring and dreaming about a Lexus? Exactly, you haven’t. The Seville is a different type of animal, and it’s the type that I love.

The specific model I’m talking about is the 2000 Seville STS. Sure, you can get the cheaper and plusher Seville SLS, but you’re basically getting a Deville in re-organized packaging. When you say, “Yeah I just picked up a Cadillac STS” people instantly know what I’m talking about. Try saying the same thing, only say Cadillac SLS. It doesn’t work; people seem confused. Still, regardless of what model you pick up, this car is an excellent value on the used car market. Take my “new” Seville STS for example. My car is a ’00 STS with 54k miles; Sterling Silver w/ Pewter interior. Fully loaded, only missing the Navigation system and sunroof. The sticker for this car brand new easily topped $52k. However, I just picked up this clean example complete with new head gaskets, water pump and motor mount for only $10,700. Yes, this 8-year-old car only cost me $10,700. Amazing, and that’s only the beginning.

Cadillac was on the emergence of a great renaissance when this car was introduced in late 1997. Not only was this car a huge improvement over the already great model it replaced, it was a huge hit with automotive journalists alike. Sales, on the other hand, dropped almost 11k units in the 1998 model year. Why you ask? Price. The base price for a ’98 SLS was almost $43,000 while the STS went for a staggering $46,000. This might sound reasonable to a Cadillac loyalist, but this car was up against some stiff competition. BMW had it’s excellent new for ’97 5-series, Lexus had its ultra refined GS400, and Mercedes had it’s super elegant E-Series. Suffice to say, sales floundered and the car went out of production in 2004 to make way for the brand new STS (minus the Seville moniker). However, there are Seville loyalists (like myself) who think this is the best modern Cadillac yet. Sure, there are a few downsides to owning this car, but they are worth accepting.

I have to say, this is the most beautiful and elegant looking sedan to ever come out of Detroit. Hell, it may be one of the best looking cars ever put into production. Sure, the new CTS and STS are impressive efforts, but none of them do it for me like the Seville STS. The car is perfectly executed, from the front grille to the rear taillights and everything in between. Cadillac was at its absolute highest from a design standpoint when this car was put into production, and there are few cars that “do it” for me like the Seville does. It turns me on, no matter where I see one or what kind of mood I’m in. I swear, I think I have a Seville monitor in my head, because I can always spot one coming down the road. The car looks stunning in Crimson Red, a lighter shade of burgundy, Sable Black, which is just badass. White Diamond is typical Cadillac, typically elegant. Sterling Silver is very clean, sophisticated, and sexy. Another of my favorite is Polo Green, an extremely rare color that looks black from a distance. The other colors are no match for the body of the Seville, and just dull the cars look. The ’98-’01 Seville SLS have a plain silver colored grille, ugly plastic molding on the bottom, and cheap wheels that look out of place on a car of this caliber. Starting in 2001, you could order a “STS Appearance Package” which added a body colored grille, 16” 7-spoke chrome wheels, body color appearance molding, among other things. This package became standard in 2003; the STS pretty much stayed the same throughout its 5-year run, with the exception of 2001 when Cadillac offered a STS Sport Package, which offered larger 17” 6 spoke wheels and other accessories. In 2002, both SLS and STS models left behind the old Cadillac logo in favor of the new “Art & Science” logo first introduced on the CTS. Other than this few appearance changes, there was nothing to distinguish the cars year to year. Only true Seville loyalists could spot these changes.

The interior of the Seville has its ups and downs, very unlike the exterior. At first glance, the car looks of the highest caliber, using exquisite leathers, high-end gauge clusters, smart controls, and beautiful wood trim. Unfortunately, this is quickly downplayed when looking closer. The headliner is made of a cheap, mouse like material found in Chevrolet’s, the plastics used on the door jams and around the console area is GM Corporate, which means of the lowest caliber. You can pull the A-pillar material off with one hand, and the weather-stripping around the door needs to be reattached on several occasions. However, none of this really matters to me. If I would have paid $53k for the car brand new, yeah I would have been disappointed with the materials. However, I’m not complaining one bit at $10k. Another thing I’m not complaining about is the features. Damn, this car really brings a new meaning to the phrase “fully loaded”. Power leather memory seats, Bose 425 watt sound system, 6-disc CD changer, and optional navigation system. Sure, most modern cars have self parking assistance, lane change warning and other useless crap you don’t need, but for a late 90’s car the Seville has everything a person would want. I’m personally the most fond of the Bose stereo, which I have still not found a suitable match for. Even the new STS with its 15-speaker system still can’t match the Seville for sound quality. This blows the competition away of the same area, with the exception being the LS400’s Nakamichi sound system. However, you might not need the Bose system at all…

…You might instead be listening to the Cadillac Northstar V8. Yes, the engine that practically saved Cadillac in the early 90’s is installed beneath the bonnet of this sexy machine. All 300 horses are driven through the front wheels, and it’s probably one of the best exhaust notes this side of a Ferrari or Porsche. The car has a typical V8 snarl when being started up, but it really shines when you floor it. You can get some serious trouble when driving this car. Most Seville’s never have the chance to be driven hard, since they are owned by old ladies driving to church. For this single reason, is why most people experience problems with the Northstar engine. The engine is extremely reliable if well maintained. The key to a strong running Northstar is changing the coolant. GM recommends the Dex-Cool get changed every 5-years/150k miles; I wouldn’t go by this, I would get it done every 3-years/48k miles. This way, you don’t have to worry about the engine blowing a head gasket. Also doing regular WOT (Wide Open Throttle; a.k.a mash that bitch to the floor) will help keep all the carbon deposits cleaned out. Do those few things (along with changing the oil of course) and you should be able to get 200k or more miles out of the Seville and its Northstar.

Ok you’ve heard me ramble on about the seductive styling, nicely laid out interior, and powerful engine, so how does it drive? Well, what do you think? It’s a Cadillac, so it has a smooth ride that soaks up the bumps like no other. It’s not super soft like the Deville, but no overly hard like the CTS. The ride motions are well controlled, and the handling is superb for such a heavy FWD sedan. It takes the corners with ease, and there is little understeer to be detected. However, if you want BMW handling this isn’t your car. The car does have a little more body roll than your average sports luxury sedan, but it isn’t anything 90% of people complain about. It feels confident throughout the ride, and the only hint of torque steer is when mashing the accelerator when exiting a corner. Overall, I give it a 7.5/10. In late 2002, Cadillac introduced the Magneride suspension for the Seville STS (and to be introduced on the 50th Anniversary Corvette) and was a marvel if anything. It uses a special fluid to adjust shock rates depending on the road. From what I have read, handling was largely improved and finding a late example ’03 STS is the best deal on the luxury market today. I haven’t had a chance to drive a Magneride equipped car, but I hope to in the near future.

The Cadillac Seville STS represents the best value on the used luxury car market today. Modern styling, loads of electronic goodies, powerful Northstar engine, great handling, and a low price makes the car the best of the best. You can find plenty of low mileage, good conditioned cars for under $10k. The ’03 STS w/ Navigation, Sunroof, and around 40k miles will set you back a very reasonable $15k. Not a bad deal for a car that stickered for near $60k when it was put to sleep. Now, I have an assignment for you: find a low mileage Lexus GS400, BMW 540i, or Mercedes E420 w/50k miles for under $14k. Might be a little harder than you think…

I think I detect a note of Irony here from the previous post. seriously, it was great to reread the writeup, very well written and lucid. Oh and the car is great too, ever notice after a rainstorm when you pop the trunk to get something, where all the water goes, yep right down your neck. lol

It's been another month since I have posted about my Seville and nothing else has changed. I'm still dealing dealing with my more annoying than ever "Service Theft System" message on the DIC. I'm to the point now where I'm just ignoring it, because I'm sure it's a very expensive fix that isn't worth it on a $6k car.

My brakes were vibrating very badly so I finally took it in to repair them along with the inspection sticker. Turns out I had less than 2/32 on the rear pads and my fronts were warped. Got the whole shebang done for around $190. Not bad at all; also got them turned just to make sure I don't have any more problems. Brakes are smoother than glass; i've had the car since June 30th 2008 and they have never been this great.

My noisy "strut" has turned out to be the swaybar bushings; eventually I will get them replaced. For now, I'm going to ignore the squeeking. Best way is to turn up the radio and you can't hear a thing. :)

Still adore the car very much, though if I did it all over again I would definitely purchase a MagneRide '02-'03 STS in Blue Onyx, Black, White Diamond, or Crimson Red. Not that I don't love Sterling, but those 4 colors are my Top 4 favorite (in the correct order).
